TMPR4937XB-300/333 (TX4937)

64-Bit RISC Processor

Description

The TX4937 MIPS RISC microprocessor

is a highly integrated ASSP solution

based on the Toshiba TX49/H3

processor core, a 64-bit MIPS I, II, III

Instruction Set Architecture (ISA)

compatible with additional instructions.

The TX4937 has integrated peripherals

such as SDRAM memory controller, PCI

controller, PIO, AC-Link, UART and

timer. This class of product is targeted

for applications that require a high-

performance and cost-effective solution

such as networking and printers.

Features

• TX49/H3 core with an integrated IEEE

• 4-channel SDRAM controller
